The nearby radio galaxy Centaurus A (NGC 5128) hosts a rich system of stellar streams, shells, and a thin co-rotating plane of satellite galaxies sharing the same rotation sense (Malin 1983; Müller 2018; Libeskind 2015; Pawlowski 2018). The combination of strong coherent tidal streams plus a whirling satellite plane is reproduced in fewer than 1% of comparable ΛCDM simulated halos.
The standard model expects satellite systems around massive galaxies to be roughly dispersion-supported and only mildly anisotropic. The CenA configuration combines two anomalies (coherent stream system + co-rotating satellite plane) that should be largely independent under standard accretion physics. Joint occurrence at less than 1% per simulated host system has no clean source in the model.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, the Centaurus A stream system is a cascade-debris fossil signature linked to its co-rotating satellite plane through shared cascade-J inheritance. CenA + its satellites + its stream debris all formed together as cascade-debris siblings of the same parent cascade event, all inheriting the same parent J vector at deposition (P22, P25, P31, P32).
The streams and shells are cascade-debris fragments that did not coalesce into bound satellite galaxies but settled into stream-orbit configurations within the CenA gravitational potential. The satellite plane co-rotates with these streams because both share the same inherited cascade-stream J. Sibling pockets (P58, P59, P60) extend the coherence to multi-Mpc scales, providing the broader cosmic-environment alignment of the CenA system.
Gravitational superposition (P50, P51, P52, P54) gives the apparent dynamical mass of the CenA system without invoking exotic CDM particle halos: the Φ_mesh contribution from CenA + cosmic-web mesh provides the binding. The same M3 framework that produces the MW VPOS (recid 130), the M31 satellite plane (recid 131), and the Sagittarius stream system (recid 135) produces the CenA observations as a unified cascade-J-inheritance fossil. There is no need to invoke special accretion histories or fine-tuned orbital geometries.
If precision JWST + LSST + Roman CenA-region surveys find the streams and satellite plane uncorrelated in J orientation (no shared cascade-J inheritance signature), the M3 cascade-fossil explanation is refuted. The signature SCT prediction is the CenA stream J vectors aligning with the satellite-plane rotation direction at the cascade-stream-event level.
